# OID Example: Batch Processing
# =============================================================================
# Use VPN for data processing jobs that need IP rotation or region-specific access.
#
# This example demonstrates using OID for batch processing tasks like:
#   - Web scraping with IP rotation
#   - Data collection from region-locked sources
#   - API calls that require different IP addresses
#
# Usage:
#   1. Place your .ovpn file in configs/client1.ovpn
#   2. Run: ./examples/batch-processing.sh
#   3. Process data through the VPN
# =============================================================================
